Abstract

The embodiment of the invention discloses a driving method, a display panel and a display device. The driving method is applied to the display panel. The display panel comprises a plurality of displayareas which are horizontally arranged, wherein one display area is a reference area, other display areas are to-be-corrected areas. The display panel comprises a source electrode and a common electrode, and the driving method comprises the following steps: obtaining a common electrode feedback voltage in a reference area and a common electrode feedback voltage in a to-be-corrected area; compensating the source voltage of the to-be-corrected area according to the common electrode feedback voltage in the reference area and the common electrode feedback voltage in the to-be-corrected area to obtain a compensated source voltage; and outputting the compensated source voltage to the source of the corresponding to-be-corrected area. The reference area serves as a reference, the source voltage ofthe to-be-corrected area is compensated, the deviation value of the common electrode feedback voltage in each area relative to the source voltage is adjusted in a source voltage compensation mode, and the display effect is guaranteed.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to a driving method, a display panel and a display device. Background technique [0002] With the development of display technology, liquid crystal display devices are favored by a large number of users due to their advantages of small size and low power consumption. A liquid crystal display device generally includes a backlight module and a liquid crystal display panel, the backlight module is used to provide light for the liquid crystal display panel, and the liquid crystal display panel is used to display text, images and other information. When the liquid crystal display panel displays text, images and other information, if it flickers, it will affect the display effect. [0003] The pixel points on the liquid crystal display device are driven by the pinch voltage formed by the source voltage and the common electrode voltage applied to both ends of the pixel poin...
